When a sound intensity increases by factor of 10 it's decibel reading increases by blank?
Decibel Scale [Apex] (: its 10 honey
How many times louder is an 80 dB sound compared to a 40 dB sound?
1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.1000 times louder. Every 10 decibel, the intensity increases by a factor of 10.
An increase of 20 dB increases the sound intensity by a factor of?
A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.A factor of 100. Every 10 dB, the intensity increases by a factor of 10.
How many times louder is a sound wave with a intensity of 83db than a sound wave with an intensity of 70db?
Use the definition of decibel. The factor can be calculated as is 10(83-70/10). = 101.3.
How is intensity related to loudness?
Assuming we are talking about sound, intensity measures the power in a sound wave. Mathematically, it is the product of the sound pressure and the particle velocity, and is measured in watts per square meter. Loudness usually refers to the (subjective) perception of sound intensity by people. It is related to intensity, but also depends upon frequency. The human ear perceives increases in sound intensity roughly on a logarithmic scale, so for example the sound intensity needs to increase by about a factor of ten to create the perception that the sound is twice as loud. This is the motivation for the decibel system, which measures sound intensity on a logarithmic scale.

How does the intensity of a sound wave change if the distance from the source increases by a factor of 2?
The intensity increases by a factor of 4-APEX
How will an increase in amplitude and power affect dB?
The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB. If power increases by a factor of 100, that is equivalent to +20 dB.The decibel (dB) scale is logarithmic. An increase of power by a factor of 10 is an increase of +10 dB.

How do you double decibels?
When doubling the field quantity factor by 2 the level increases by 6 dB. When doubling the energy quantity factor by 2 the level increases by 3 dB. When doubling the sound pressure value by 2 the level increases by 6 dB. When doubling the sound intensity value by 2 the level increases by 3 dB. The decibel (dB) is a logarithmic unit that indicates the ratio of a physical quantity relative to a specified or implied reference level. You usually don't double decibels - you double the factor (ratio). Look at the link "Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power)".

How is the energy of a sound wave related to its measured value on a decibal scale?
The decibel scale is a logarithmic scale. An increase of 10 points on the decibel scale means that the energy increases by a factor 10; an increase of 20 decibels means an energy increase by a factor of 10 x 10 = 100, etc.
What does a decibel measure?
Decibels measure a ratio of two values of the same unit.Answer:A decibel is measure of loudness of sound although it can be applied to other applications. The base unit is the bel and a tenth of that the decibel. In the real world a decibel of sound is about the weakest sound a person can hear - as an example the rubbing of your finger and thumb together at arms length.
What measures decibels?
A decibel usually measures power or intensity. Most common application are in Audio levels. A decibel(dB) is actually a ratio of the measured physical quantity to a standard reference value of the same physical quantity. It is expressed in logarithmic scale. As we have in decigram, decimeter similarly a decibel(dB) is also one tenth of a Bel. A 1 Bel (10 dB or decibel) change represents multiplying the intensity or power level by a factor of ten. It becomes easier to express things in decibel as they are short numbers compared to the real physical measure.
How does the intensity of a sound wave change if the distance from the source is reduced by a factor of 4?
- 6 dB is incorrect. It will decrease by 12 dB.
